I am looking for providers such as Saily that offer data volume/mobile data abroad (in my case the USA) via eSIM. However, with the providers I have found, you have to register via Google or Apple to be able to use this. Do you know of any alternatives for degoogled customROM such as /e/OS? Or a way to get around this?
I currently use a German network operator for my SIM.
It should be an eSIM option, as I only have one eSIM and one SIM slot.
Now that yesim works for you there’s possibly no need for further search. But still you might have a look at this wiki or even update it with your experience:
